Nesting avro with avro or proto binary represenations

[Shirahatti, Nikhil]

Hello Avro Users,

My question is whether we can use an avro schema as a wrapper for another 
avro/protobuf binary representation.

Example:

{

      "namespace": "com.AvroExample",

      "name": "wrapper",

      "type": "record",

      "fields": [

          {"name": "timestamp", "type": "long"},

          {"name": "header", "type": "string"},

          {"name": "body", "type": "bytes"} ]

}


Then the body can be filled in with the binary representation 
(avro/protobuf/json). Can we wrap the below avro schema being inside the above 
wrapper schema? If so any pointers for it?

{

      "namespace": "com.AvroExample",

      "name": "server",

      "type": "record",

      "fields": [

             { "name" : "status", "type": "string"},

             { "name" : "user", "type": "string"}]

}


Thanks,

Nikhil
